This stone is hardcore. It eats up steel so fast that it makes serious repairs & bevel-setting a dream. Most straight razors will never need to see this stone, but it’s ideal for desperate situations such as removing serious chips, especially from ultra-hard razors like those from Portland Razor Co. or Thiers Issard.
Naniwa Professional stones are harder than most, so they stay flat better and last much longer than cheaper options. This stone is also great for both starting and finishing pocket knives & bushcrafting knives, or for starting your hunting knives.
